Earnest TEL. NO: 209-583-5571 <br /> BACKGROUND: <br /> Ultramar purchased site from Conoco in July 1990 Several <br /> ground-water monitoring wells had been installed by Conoco <br /> (formerly Kayo Oil Company) at and near the site. At the time <br /> of site purchase, all but six wells (RW-1, MW-16, MW-18, <br /> MW-20, MW-21, and MW-25) were dry. <br /> In March 1991, one additional ground-water monitoring/vapor- <br /> extraction well (MW-27) and one vapor-extraction well (VW-26) <br /> were installed as part of the installation of a vapor <br /> extraction system designed and permitted for the site. Soil <br /> and ground-water analyses showed nondetectable to moderate <br /> TPHg and benzene concentrations. <br /> Permitting for the system was completed and the vapor <br /> extraction system was installed early in the third quarter <br /> 1991 . <br /> A permit application for a 500 scfm catalytic incinerator was <br /> approved by the APCD and the system was initiated on September <br /> 20, 1991. <br /> During tank replacement activities, first quarter 1994, 15 <br /> underground storage tanks were removed from the property. <br /> Eleven of these tanks were unknown prior to the tank removals. <br /> During the first quarter 1994 three groundwater monitoring <br /> wells and a groundwater recovery well were installed. Also, <br />. twelve vapor extraction borings were drilled with three or <br /> four "nested" wells in each boring. <br /> o IEQO®a <br /> A Member of the Ultramar Group of Companies <br /> #1 Quality and Service <br /> ufhamar <br />
